BACKGROUND OF THE INVENTION Field of the Invention

This invention relates to a duct interface device that can be used to easily and effectively connect a new air conditioning or heating duct to an existing register box.

Background of the Invention

It is well known in the industry that when contractors put register boxes into new houses, they often do not think of how difficult it will be to access and replace the ducts to these boxes, as the initial installation is usually done before ceilings are installed. It is much easier to get on a ladder and place a register box in between ceiling studs than, 10 years later, when the heating ducts need to be replaced, to climb into the attic and try to wiggle your body into position to detach the old duct and attach a new one.

Thus, there has existed a long-felt need for a device that allows an HVAC worker to easy, safely, and effective access a register box, remove the old duct and attach a new duct.

The current invention provides just such a solution by having a duct replacement device and method of use provides a duct sleeve flex connector, in three different versions, each with a flat, rigid metal bar with thin, metal bracing strips and a female-treaded pole hinge. After cutting loose the old duct from under the register box, an HVAC technician enters the attic and threads the device on a telescoping pole, depositing the device near the open register box. The technician then climbs a ladder under the register box, grabs and adjusts the device with the flat, rigid metal bar into position, then attaches it with the thin, metal bracing strips.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated.

DETAILED DESCRIPTION OF THE FIGURES

Many aspects of the invention can be better understood with references made to the drawings below. The components in the drawings are not necessarily drawn to scale. Instead, emphasis is placed upon clearly illustrating the components of the present invention. Moreover, like reference numerals designate corresponding parts through the several views in the drawings. Before explaining at least one embodiment of the invention, it is to be understood that the embodiments of the invention are not limited in their application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The embodiments of the invention are capable of being practiced and carried out in various ways. In addition, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

FIG. 1 is a perspective view of a cylindrical version of the invention. Note how the invention 101 has a duct sleeve 108, that fits into an inner circumference of a new duct, and a crimped male end connection 109, that fits into a boot of a register box. The female-threaded pole hinge 104 mates with a male-threaded telescoping pole 107 such that a work can maneuver the invention over a register box and deposit it there, rather than having to crawl into tiny crevices under the roof to get to the register box. A flat metal bar 102 extends from one side of the invention to the other and serves as a grab bar for a worker to grab the invention, pull it down into the boot of the register, and maneuver it into position. Two thin metal securing straps 103 are then bent to the appropriate shape and screwed through the register box into the surround wooden studs.

FIG. 2 is a side view illustrating the general layout of a duct and how the invention works to make replacing a duct safer, easier, and more efficient. Note how with the telescoping pole 107, the invention can be located right over the register box, without requiring the HVAC worker to crawl to the register box.

FIG. 3 is a perspective view of a box-like version of the invention. Note how the invention has one end that fits inside the new duct, and can be attached to it, such that the telescoping pole can “lead” the invention, with the new duct in tow, to the register box.

FIG. 4 is a cut-away side view of a house showing the difference in “ease of replacement” between a traditional HVAC worker and one using the invention. Note how when initial contractors locate register boxes, they don't think about how difficult access may be once a ceiling is put in and a roof is installed.

FIG. 5 is a cut-away side view of a house showing the problems encountered by a traditional HVAC worker trying to access a register box located and a tight corner under the roof.

FIG. 6 is a perspective view of the 90-degree bend version of the invention. In this version, the parts are very similar to the version shown in FIG. 1 , but there is a 90-degree bend in the invention such that the new duct does not have to bend (and become in danger of crimping) as it reaches the register box.

FIG. 7 is a perspective view of the box version of the invention. This version is designed for very narrow areas, with the box duct assembly 119, provides an extension of the metal invention features in FIGS. 1 and 6 , such that there is no need to risk crimping the new duct as the HVAC worker tries to connect it to the register boot.

FIG. 8 is a side view showing a detail of the female-threaded pole hinge.

FIG. 9 is a cut-away side view of two HVAC workers coordinating the depositing of the device at the end of a new section of duct.

The following is an explanation of how the invention works:

In the HVAC field, the installation of a complete central a/c & Heating system consist of a number of steps. Some of the main components are 1) The outdoor condenser unit which is used to compress low pressure gas into liquid in order to remove heat from a conditioned space. Another main component is the Air Handler or FAU (125) (forced air unit) which is connected to an evaporator coil. The air handler uses a blower motor to move warm air across a cold evaporator coil in order to cool the warm air and distribute chilled air through a Duct System. This Duct system (FIG. 2 ) Has a Main Distribution Branch called an Air supply Plenum (124) which is typically square or rectangular in shape and made out of sheet metal. The rigid metal Air supply plenum (124) Has smaller round air supply Branches connected and tapped into it called flex Duct (110). The purpose of a flex Duct (110) is to distribute a controlled amount of air (CFM) to a space (FIG. 2 ) of the appropriate square footage. The more air required; the Bigger the Diameter of flex duct (110) will be required. For example, a bathroom typically requires a 5″ Diameter flex Duct while a Bedroom would need an 8″ flex Duct (110) in order to cool the room properly. (FIG. 3 ) Flex Duct (110) are typically made of a thin mil plastic over a round metal wire coil to shape a Tube (117). The tube is insulated with a glass wool (116) and covered with a thin outer layer (FIG. 3,118 ) made of polyethylene or metalized PET that is a vapor barrier (FIG. 3,118 ). The Flex Duct (110) is connected from the supply Plenum (FIG. 2,124 ) to

An air register Box (112). A supply register Box (112) is a square or rectangle shape box that is made of Sheetmetal. This box has a round Diameter boot (113) that is tapped into the center of the box. The boot (113) on the register box (112) is for the purpose of Connecting the end of a flex Duct (110) to the Register Box (112). The register box (112) is the open-end ride for the conditioned air that is introduced into the conditioned space (FIG. 2 ).

During the New construction phase of Building, register Boxes (112) are hung between the ceiling rafters in each room and living space during the Framing stage before the Drywall is installed in the building. During this time is also when the flexible duct system will be ran above the ceiling in the Attic space. Multiple Flex duct runs (110) of various Diameter sizes and Lengths of flex Duct (110) ranging just a few feet to many feet are ran all across the attic space of the building. It is at this time that a proper Flex Duct (110) to Air Register box (112) connection is Made. A proper Flex Duct (110) to Register Box (112,113) connection is Very important to prevent air leakage when the FAU (125) is distributing air to the conditioned space. Air Leakage in Ducts cause inefficient A/C operation and very costly troubleshooting procedures to correct if a HVAC technician has to trouble shoot to locate the air leak after the building has been completed and the A/C System has been installed. A leaking Duct repair would very difficult because with attic insulation, water pipes, gas pipes and wires etc. . . . running across the attic, making the attic space too narrow to reach the leaky Duct Connection without removing sections of ceiling Drywall in order to access the leaking Duct connection FIG. 5 140. Also, the leaky Air register (112,113) to Flex Duct (110) connection maybe in a tight very narrow corner space in the attic (FIG. 5,140 ) near a window which is typical. This is why it is Very important that a Flex Duct (110) to Register (112,113) be Airtight.

A proper flex Duct (110) to air register boot (113) is made with the following steps.

First the installer must strip the existing flex Duct to register box Boot (113) bare removing all sealer tape and zip ties or clamps, then dispose of the old Duct. Next the installer will then take the end of the flex Duct (110) (FIG. 3 ) peel back the protective mylar jacket (118) (FIG. 3 ) and glass wool insulation (116) exposing the plastic and wire tubing (117) 3-4″. Next connect the plastic round tubing (117) over the sleeve of the register box boot (113) overlapping the sleeve 2-3″ then secure the connection with a plastic zip tie fastener (126). Follow up by Taping over the connection with duct tape. Next pull the glass wool insulation and mylar membrane (116, &118) over the coiled plastic tube (117) & register boot connection (113) and tape the outer membrane (118) and Glass wool insulation (116) to the register boot (113) with Duct tape then secure that connection with one more zip tie fastener (126). After the flex Duct (110) & register boot connection FIG. 2.5 (128) is secure brush mastic duct sealer on to the connection to ensure a permanent and airtight connection. Steps are to be repeated for all Air registers (112) in the building.

In summary what has been written so far explains what a flexible Duct system is and how it works. It was also explained how a flex duct (110) to air register box (112,113) connection is achieved and how important it is that it be airtight. Another point I would like to make is that for an experienced HVAC worker it is fairly easy to run a flexible Duct system in the new construction Phase. It is easy because the Attic space is open with no obstructions. The installer is free to move around and lay long runs of flexible ductwork (110) all across the attic with ease.

In the construction phase of A building, HVAC trade workers are usually one of the first trades in to work right after the rough base framing of a building has been done. HVAC workers usually lay Ductwork (110) ahead of plumbers, electricians and Drywallers. This is because ducts (110) are big and bulky and other trades have slimmer water pipes, electrical wires, communication cable, gas pipe, which all can all be installed under, over and around bulky Flex Duct (110.). It typically does not work better vice versa.

Once a Building is complete and all the trades are finished. The attic is no longer open. The Dry wall ceiling has been put up. Gas pipes, water pipes, communication cables, light Ballasts, electrical wires, exhaust vents Duct work and cross braces are everywhere! The attic is Now a crowded and Dark dangerous place!

So, let's say 25 years have passed since this building (house)(FIG. 5 ) was built and it has been occupied all of its life. So, after 25 years the owners want to get rid of all their old duct work (110) and install all new Duct work (110) in the attic. Installing new Duct work (110) isn't going to be so easy now. There is going to be some access challenges in the now crowded Dark attic space. The Duct Installer must now come up with a clever plan. ESPECIALLY FOR AIR REGISTERS (112) CONNECTED IN A VERY NARROW SPACE LIKE NEAR A WINDOW FOR EXAMPLE (FIG. 5,140 ). To begin the Job, First he must remove all the existing ductwork (110) which requires him to crawl in the attic in narrow spaces most of the time he will be stretched out strait on his belly (FIG. 4 &FIG. 5,140 ) across the ceiling rafters reaching out with both hands to cut out and disconnect the old and existing very secure flex Duct end (110) to register box boot connection (113). This is a Very Dangerous position for a Duct installer to be in as the attic is very hot in the summer and prolonged time in the attic can cause dehydration, heat exhaustion, cramps, stroke, heart attacks, which all can lead to Death. The installer being in an awkward position in the attic is also at risk from falling through the Drywall or getting electrocuted by a bare electrical wire he did not see but laid over. An installer hitting head on a rusted roof nail is also all too common in the HVAC trade when installing duct work. The above-mentioned risks are just the tip of the iceberg in what can happen while installing a new Duct system. Besides the safety issue there is the economic issue. All too often when installing a Duct system, the installer will swipe his feet across a thin but very important network cable or accidently put his foot or knee trough the Dry wall ceiling maybe snap a water line and flood the attic causing the ceiling to collapse. Things like this happen all the time and hiring a professional to fix what the duct installer broke cut a hefty slice out of the A/C companies' profits for that job. Many times, it is so severe the company will take a big loss on the accident. Injury and property Damage! the risk lists are endless when it comes to replacing old Ductwork with new Ductwork in an attic. All the scenarios explained above are common. This does not mean that every duct system change out in an attic is a death trap. Not at all. The TRUE problem is the 1 or 2 air registers (112) out of the 10 that are fixed in very Narrow hardly accessible spaces in attics (FIG. 5 ) (140) (112). These hard-to-reach duct connections are known as killer Ducts. This type of Duct connection stares a duct installer deep in their eyes and spitefully whispers “you can't change me, I'm untouchable, you're not good enough! Fat man!”. The whisper dares and challenges the maybe not so athletic duct installer to low crawl on his hands and knees dragging his belly across the rafters with cutting tools and snips in pockets stretched out reaching for the Duct connection in real agony (FIG. 5 ) (140). If the installer does disconnect the flex duct (110) from the hard-to-reach air register (112) successfully the installer will then have to go back again and reconnect the new Duct which is an even harder task than disconnecting. It's during this time that disaster can happen. Even if the Duct installer does prevail in changing the hard-to-reach duct connection without serious injury or property damaged. He is not unscared from the rough experience. Sore elbows and glass insulation fibers from a mouthful often do tickle the tonsils leaving a mental syndrome when another killer duct stares him in his eyes. So, when the traumatized Duct installer is in the attic and sees another flex Duct to air register connection in a Very narrow attic space. This time he might not want to put himself in that uncomfortable position he once was in again. So, this time he might just leave the old existing Duct connection in place and splice onto that old flex duct (110) a few feet back with new flex duct (110) where the installer is within reach to work comfortably. Doing this lowers the efficiency of the entire A/C system because the old ducts that were left in place are most likely leaking air into the attic and not the intended conditioned space. This unethical type of practice is habit forming and is highly addictive amongst Duct Installers WorldWide. When added up on a grand scale the carbon footprint is tremendous. This type of practice must be eliminated.

Currently there is no known method or product on the market that solves this problem. Therefore, I propose my original product, design and method that makes it much easier and safer for a duct installer to disconnect an old flex Duct connection from an existing hard to access air register (112) (110) and install a new flex Duct connection onto the existing Hard to access air register (112) located in a narrow attic space. My new original invention makes it much easier and safer for a duct installer to install a hard to access flex duct (110) Branch while safely connecting the flex Duct end (110) to an Air Register Boot (113) without needing to physically make the duct connection or seal the Duct connection while inside the attic space. My new original invention product also eliminates the need to crawl through an attic space up to air registers (FIG. 4 ) (140) for the purpose of disconnecting the Flex Duct (110) from the Air register (112) Boot (113). My new original invention also eliminates the need to crawl up to Air registers trough an attic space with a Flex Duct End connection (110) in Hand for the purpose connecting the duct end connection (110) to the air register (112) Boot (113) in the attic.

My new original invention and product is called the Fish-A-Duct (101). The fish-A-Duct (101) is a round sheet metal Duct sleeve flex connector that has a female treaded (105) pole hinge (104) connected to the body of it. The female threaded pole hinge (104,105,106) connected to the Fish A Duct Assembly (101) Allows a Duct installer to insert a male threaded (123) lengthy telescopic pole (107) into the female threads (105) of the pole Hinge (104) making it possible to fish the Fish-A-Duct (101) sleeve with a length of flex Duct (110) connected to one end FIG. 1 (108) through a very narrow space in the attic very near where a Hardly reachable air Register (112) is located. The fish a Duct sleeve (101) also has a flat rigid metal bar (102) that is riveted permanently across the inner circumference of the sheet metal Fish A Ducts body (101). The Flat metal Bar (102) is for the purpose of a gripping Handle (102) for the fish a duct (101) so the installer can pull, push, and position the Fish A Ducts crimped male end connection (FIG. 2,109 ) into the female boot (113) of the air register box. The Fish A Duct Also (101) has multiple ½″ thin metal bracing straps (103) that are attached to the Fish A Duct Assembly (101). The bracing straps (103) are up to 12″ in length. One end of the Bracing strap is permanently riveted to the inner wall of the Fish A Duct sleeve and the other end of the Bracing strap (103) is free until it is time to Install the flex A Duct and Brace it down to the inner walls of the metal Air register (112). The bracing straps (103) are rotatable 360 degrees. The unanchored free end of the bracing straps (103) remains in the upward position sheltered inside the fish a duct assembly (101) until it is time to install the Fish A Duct (101).

The fish A Duct (101) connection That will be fished by pole (FIG. 4,107 ) and Dropped near the hardly reachable air register (112) in the narrow attic will have a length of Flex duct (110) connected to one end of the fish a duct sleeve (FIG. 1, 108 ). This method eliminates the need to crawl up to the supply register (112) on hands and knees through the narrow attic space with a flex Duct end connection (110) in hand in order to take the flex duct end connection near the air register boot 113 FIG. 5, 140 ). The proper use of the Fish A Duct product (101) Goes as follows. The duct installer will take the lengthy pole (107) insert and screw the male treads (123) into the female threaded hinge (104) lift the Fish A Duct (FIG. 4, 139 ) and guide the Fish a duct connection (101) with Flex duct (110) through the narrow attic space laying the flex duct (110) and the fish a duct connection (101) near the intended air register (FIG. 4 —112)(. Once the Fish A Duct connection (101) with Flex duct (110) is less than 12″ away from the intended air register (112) to be connected, the installer will then unscrew the telescopic pole (107) in reverse motion loosening the poles male threads (123) from the female threads (105) of the pole hinge (104) totally disengaging the pole (107) from the fish A Duct assembly (101). This action will leave the entire fish A duct assembly (101) and the length of flex Duct (110) connected to one end (FIG. 1 —108) of the fish A Duct sleeve within 12″ from the intended air register in the attic. Before the new Fish-A-Duct connection (101) can be connected to the existing air register (112) the old flex Duct connection (110) must be disconnected from the air register (112) Box. Typically to remove the existing flex Duct connection from an air register boot (113) in a narrow hard to reach space a duct installer will have to crawl on his hands and knees with a knife and some cutting pliers trough a narrow attic and get up face to face with the air supply register (FIG. 5 —140, 112) in order to cut through the flex Duct (FIG. 3 —110), Duct tape, hardened mastic and plastic straps. After the connection is removed. The entire length of the flexible duct (110) can be removed from the attic and disposed of. Disconnecting a flex Duct (110) from a register box (112) in an attic is a very difficult task especially when the attic is very narrow and you barely fit in the cavity workspace (FIG. 5-140 ). However, Using the fish A Duct method of removing a flex duct (110) connection from air register boot (113) the task is not so Difficult. First the installer will exit the attic and enter the living space (141) where the target air register (112) is located. He will then locate the target air register (112) in the ceiling. He will then put up a ladder, climb up and remove the air register grill ( ) of the target air register (112) exposing the sheet metal register box (112)) inside the register Box (112) the installer will look up and see the plastic and coiled wire internals of a flex Duct (FIG. 3 —117).

Next the installer will take a sharp knife and cut the flex Duct (110) out from the inside out. The installer will then take his wire cutters and cut the wire that is fused on to the thin plastic sheeting (FIG. 3 —117) disconnecting the flex Duct (110) entirely from the sheet metal boot (113) of the register Box (112). The old length of Duct (110) that was connected can now be removed from the attic and disposed of and the new length of flex duct (110) can be fished in and placed near the air register by pole (107) with the Fish A Duct assembly (101) connected to it. Now standing on the ladder in the living space (141) the installer looks up into the air register (112) in the ceiling and sees the round female Boot (113) sleeve of the air register Box with no Duct connection. The Duct installer on the ladder in the living space (141) will now stick his hand through the supply register Boot opening (112, 113) into the attic and grab the nearby Fish A Duct assembly (101) by the flat gripper bar (102). The open end of the Fish A Duct assembly sleeve (FIG. 1 —109) that does not have the flex duct end (110) attached to it is the round crimped male Duct connection sleeve (FIG.—109). With the Fish a duct assembly (101) now in the installers hand holding it by the center of the gripper bar (102) the installer will now align the male connection sleeve (109) of the Fish-A-Duct (101) to the female Boot (113) of the register box (112). Gripping the crossbar gripper handle (102), the Installer will now apply pulling pressure downward pulling firmly on the crossbar (102) ensuring the crimped male connection (109) of the Fish A Duct assembly (101) is snug and well positioned inside the female boot (113) of the register box (112). once a snug connection is achieved. The installer will reach inside the Fish-A Duct connection and rotate the ends of the ½″ metal security straps (FIG. 2 —103) downwards towards the walls of the register box (112). The installer will pull on a strap (103) with pliers and create tension reenforcing a snug male to female Duct connection. The installer will then anchor the tensioned strap to the wall of the register with a sheet metal screw (FIG. 2 —111). The installer will repeat this process for as many Bracing straps (103) are provided on the Fish A Duct assembly (101). The anchoring of the security straps (102) creates a permanent and seismic stability that will last for many years. The installer will remain on the ladder closely observing the seam area where the male and female connections are joined. The installer will see that there are small air gaps at the seam between the two joined connections of the Fish Duct connection (101) and the register Boot (113). The installer will then seal the gaps with a silicon or an approved sealer. Once the sealer is dry the Fish A Duct Assembly (101) to air register (112) is now airtight and complete. This process can be done even easier and faster when 2 people are involved (see FIG. 9 ). For example installer #1 (FIG. 9 —168) can be standing on the ladder (167) in the living space (141) with his arm reaching through the open air register (112) into the attic with his hand in the catching position ready to receive the Fish A Duct assembly (101) from installer #2 (FIG. 9 —169) who is in the attic space guiding the Fish A Duct (101) and Flex Duct (110) by pole (107) through the narrow attic and directly into the Hand of Installer #1 (168) who will grab it by the Gripper Bar (102) so he can make the male fish A Duct connection (109) to female register boot (113) connection. Duct installer #1 can now re-enter the attic to Help installer #2 (169) route the flex Duct Branch and connect to the air supply plenum (125) as done typically then finish the rest of the duct installation as done typically. The duct Installer is now relieved he has tried and conquered the once dreaded and Deadly mission of replacing a hard-to-reach Duct connection. He now sleeps easier at night knowing that the job that awaits in the morning comes with a lot more ease and lot less Risk of injury. He can also hold his head high knowing he gave his customer what he or she paid for which is a complete duct replacement with no old Duct work still patched in.

While Installing the Fish A Duct Assembly (101) the installer may encounter a problem with the pole hinge (104) causing the Fish A duct not to properly connect to the register boot (113) because of its mounted position on the Fish-A-Duct. For example, since the pole hinge protrudes about 4″ from the Fish A Duct Assembly (104) there may be a cross beam or a pipe near the register (112) that will interfere with clearance of the Fish a Duct (101) to the intended register (112). When faced with this situation it is not a stalemate. The installer can overcome this problem by (FIG. 8 ) taking a screwdriver and loosening the bracing screw (154) of the top pole hinge fastener (155). This action takes pressure off the bottom male peg (152) of the adjustable pole hinge (104). The installer can remove the pole hinge (104) separating the bottom male peg (152) from the mounted top hinge fastener (155). The Installer may now locate an ideal place on the Fish A Duct Assembly (FIG. 6 —161) to re-install the pole hinge. Once a spot has being figured (FIG. 6 —161) the installer will drill a ½″ round hole into the fish A Duct (122). The installer will then tear open the bag and remove the parts to the pole Hinge relocation kit (FIG. 8 ). The installer will then take the new top hinge fastener (155) from the kit (FIG. 8 ) and push the ½″ male bolt (157) through the newly drilled ½″ hole in the Fish A Duct Assembly (FIG. 6 —122). He will then take the inner washer (160) from the kit (FIG. 8 ) and loop the fastener Bolt threads (157) inside the Fish A Duct Assembly (122). The installer will then take the ½″ Nut (158) from the Kit (FIG. 8 ) and thread the bolt (157) from the inside of the Fish A Duct assembly (FIG. 6 —122)

The installer will tighten the nut (158) forcing clamping pressure between the inner washer (160) and the top hinge fastener (155) affixing the top hinge fastener (155) firmly to the Fish A Duct (122). The installer will then drill 2-4 metal screws into the pilot holes (156) on the top hinge fastener (155) reenforcing the connection to the Fish A duct assembly (122). The installer can now take the pole hinge (104) and insert its bottom male peg (152) into the female sleeve (153) of the top hinge fastener (155). The installer will now tighten the bracing screw (154) creating a tight connection between the hinge top fastener (155), the Adjustable pole hinge (104) and the Fisha a Duct Assembly (122). The installer can now install the Fish A Duct (122) onto the air register (112) without any clearance issues. So far what has been explained is the description of the Fish A Duct (101) invention and its Function. The design in FIG. 1 is the straight sleeve version of the Fish A Duct. it is one shape and variation of the Fish A Duct (101). There are in fact 2 more shapes that have the same function and wear the same hardware. They are also installed in the same method. the only real difference is the shape of the body. The First of the 2 additional shapes are the Adjustable 90-degree elbow shape Fish A Duct (FIG. 6 —122). The 90-degree elbow (122) is a cylinder shape sheet metal duct that can be adjusted to many angels between 0-90 degrees. The elbow (122) gives the installer the advantage of installing it onto a register (112) and not having to worry about air flow issues due to a kinked duct as most flexible duct runs (110) are ran horizontally then bent down vertically to a 90-degree angle kinking the unrigid flexible Duct. The installer will then have to climb through the narrow attic up to the kinked duct and place hanger strap to position the duct in a manner that it is not kinked and air can flow at maximum efficiency. Using the rigid elbow fish, A Duct (FIG. 8 —122) quickly solves any restricted air flow issues as well as makes it easier to replace a hardly accessible register (112) duct connection in the attic space. The elbow duct (122) has a flat metal gripper Bar (102) that is riveted onto the inner walls of the elbow duct (FIG. 8 —122) toward the bottom male Duct crimped connection (109). The elbow duct (122) has a number of ½″ Bracing straps (103) anchored to the inner walls of the elbow Fish a Duct (122). The Elbow Duct (122) has a female threaded (105) Adjustable pole hinge (104) fixed to the elbow Duct (122) assembly near the male flex Duct connection end (108).

The Third and final shape is the box Fish a Duct (FIG. 7 —119). The box Fish a Duct (119) is a slim and low-profile rectangle shape variation of the fish A Duct Family. The box Duct (119) dimensions Vary in size 2″-10″ height (FIG. 7 —131). 5″-20″ depth (FIG. 7 —130), and 6″-200″ width (FIG. 7 —132). The box fish A Duct (119) has a square to round transition connection (120) on the flex duct connection side of the Box Duct assembly (119). The Box Duct (119) has a pole hinge (104) fixed on the square to round transition (120) Part of the box Duct (119). The opposite end of the transition (120) side of the Box Duct (119) has a round Diameter sheet metal air supply Duct collar (150) cut in and attached to it. The duct collar (150) has a flat metal gripping bar (102) riveted to the inner walls of the Collar (150). The collar (150) also has a number of ½″ bracing straps (103) riveted to the inner walls of the collar (150) the purpose of the slim and low-profile shape makes it Ideal when there is very little space to work with when replacing a duct connection. This is when it is pretty much impossible for a human being to crawl into a very narrow attic space (FIG. 5 —140) to access a duct (110) to register connection (FIG. 5 —112). Until now the only option to access this type of duct (110) to register (112) connection in order to disconnect the duct connection for replacement would be to remove sections of drywall in the ceiling in order to access the duct to register connection (FIG. 5 —112). Using the fish, A Duct method of disconnecting a flex duct (110) to register boot (113). Installer #1 will put up a ladder locate the target air register in the ceiling, remove the register grill exposing the plastic & wire coil internals (FIG. 3 —117) and cut the duct out from the inside out. He will then take his wire cutters and cut the metal wire disconnecting the old Duct from the Air Register box (112). Installer #2 who is in the attic will pull on the opposite end of the old Duct work and remove the ductwork from the attic. Installer #1 will remain on the ladder and put his arm through the register Duct boot (113) into the attic space with his hand in catching position. Installer #2 who is in the Attic space will take the lengthy pole (107) and screw the male threaded end (123) to the female treads (105) of the adjustable pole hinge (104) that is attached to Box Fish A Duct (119). The Box Fish A duct (119) will have the required diameter and length of Duct (110) Attached to the metal flex connection collar (121) on one end of the box fish A Duct. Installer #2 will then lift and guide the low-profile Box Fish A Duct (119) through the narrow attic and directly towards the Hand of installer #1 Installer. Installer #1 will grab the box Fish A Duct Assembly (FIG. 7 —119) by the flat Gripper bar (102) installer #2 will now disconnect the pole (107) from the female threads (105) of the pole hinge (104) by turning it in reverse motion. Installer #1 will then align the crimped male collar connection (FIG. 7 —109) with the female register boot sleeve (FIG. 7 —113). The installer will then pull down applying downward pressure ensuring a snug male fish A Duct collar (109) to Female air register Boot (113) connection. Installer #1 will then rotate the bracing straps (103) downward towards the inner walls of the air register pull on the straps with pliers to create tension and then screw the tensioned Bracing straps to the inner walls of the air register (FIG. 2 —111). The installer will then inspect the seam where the new Duct connection was joined and seal all air gaps with caulking or approved sealer. The low-profile box fish A Duct is now installed.

In conclusion the Fish A Duct invention solves many problems.

#1 is safety disconnecting and replacing a duct connection to a register box ( ) in a narrow hard to reach space in an attic is extremely uncomfortable Hot and Very dangerous. dehydration and heat exhaustion are very common performing this task. Many other serious injuries can occur due to excess heat for example heat stroke and heart attack to name a few. Also, electrocution from a bare wire that the installer does not see and contacts. Deaths have been documented running duct work in a hot attic.

#2 The Fish A Duct saves time and money! It's just easier and the smartest way to run ductwork in a risky narrow attic space. Costly property Damage to a customer's home can be avoided vey simply.

#3 The Fish A Duct is Green Product 100 percent because many hard-to-reach leaky ducts never get changed out even when a homeowner pays for a full Duct replacement. The hard-to-reach ducts are simply too dangerous to replace. Now that it is possible to do so with the Fish-A-Duct.

More leaky ducts will get replaced with new airtight Ducts therefore saving energy and greatly reducing the carbon footprint on the environment.
